Every time I use Evaporust I get frustrated that the parts look *amazing* at first glance once first removed, but then quickly seem to take on a sort of residue film if I leave them lying for even for just a minute or two. Of course it stands to reason the parts should be rinsed off anyway, but as soon as I do so they look dull... as if they need to be repainted or sanded or plated or whatever. For parts that were originally "plain bare metal" this is aggravating especially if most of it had been OK except for the rusty portion, and is now uniformly dull.
I've yet to do an Evaporust treatment that left the part ready-to-use. Which is understandable to a point, but how are you folks getting away with using it without having to rework every last part after all?
